Straight Talk Wireless review: Straight talk card already redeemed! Scam?

I bought a $45 straight talk card and I tried to add the card using the automated texting number. It would not give me the option to ADD the $45 or plan. I had previously added the $35 plan so that was the only option it gave me besides “data add on” or “other” so I chose “other” and it gave me a link to go to the website to choose a different plan. I went to the website and the website wasn’t working so I called straight talk to talk to an agent and got a recording saying they were closed for updates. So I called the next day and was told my card had already been redeemed! I told her it had not been redeemed because I just scratched it the previous night and it never got added! The phone call got cut off so I called back and the new agent said the previous agent didn’t know what she was talking about and that my card was not activated correctly and told me to go to the store with my receipt to have Walmart re-scan it but Walmart said I’d get charged again if they did that and he said that it was on the receipt that my card got activated so I came home and tried to add it again via text and I got a text back saying the card was already redeemed! It has not been redeemed and I feel like I just got scammed! I’m including a photo of my receipt.
